MIAMI — A federal team investigating the causes of the 2021 collapse of a Florida condominium tower continues to focus on construction flaws in the building's pool deck. Ninety-eight people died when the Champlain Towers South condominium came down in Surfside.
A team from the National Institute of Standards and Technology has spent nearly $30 million gathering evidence and testing materials used in the building's construction. In an update Thursday at NIST headquarters in Gaithersburg, Md., investigators said tests show concrete used in the pool deck and in the columns that supported it was weaker than required by building codes.
